Surreal

I need more than an idea- a definition to give concrete form to this feeling.
Do I mistake the irrational reality of a dream for normalcy?
A disease (surra), and an artistic term (surrealism), before and after,
But the 2000 page Unabridged Encyclopedia of language omits
The mysterious adjective.
What event could this discovery portend?

My trusty watch slows 20 minutes of its own accord.
Oblivious I straggle behind the correct majority
I show my watch to explain my belated arrival is relative (isn’t everything?)
Making the connection I explain to my boss, I was late due to the dictionary.
So surreal.
